To @ZZ whom it may concern: means, the use of which, while necessary,

Be it known that I, CHARLES S. PARTRIDGE, form no part of my invention. a citizen of the United States, and a resident The upper or inner surface a of the mold of Chicago, in the county of Cook and State of A is perfectly plain, excepting that the mar- 5 Illinois, have invented certain new and useful ginal surfaces of its longitudinal side edges 55 Improvements in Stereotype-Casting Boxes, are raised to provide retaining-walls b, and of which the following is a full, clear, and exat the base of the inner inclined sides of these act specification. retaining-Walls corresponding longitudinal My invention relates to stereotype-casting channels are formed, in which the removable io boxes; and it is particularly adapted for castv longitudinal side bars B B are seated.

Arranged between and parallel with this style are the transverse expansibility of the bars B and with each other on the castthe base from one to several columns Wide ing-surfaces of the mold are removable spacand the rigidly held `channeled clampinging or partition bars C and D.

A i than at the edges or angles thereof-farthest Referring to the "drawings, A represents from said molds. the rectangular mold of a vstereotype-base- The inner or casting surface of the cover is 45 casting box, and B the Cover, preferably provided with a series of longitudinal ribsE 95 hinged thereto at one end. This box is pro- E andF F, which project from a casting-survided with the usual clamping devices and face which is on the Same horizontal plane as is swiveled in a cradle or frame C in the usual the meeting of the cover with the mold when manner and is also fitted with the customary the two are locked together. The ribs E E 5o tilting levers and other common operating project from the cover at such points that zoo when the casting-box is closed they enter the space between the partition-bars C and D of the mold, so that, together with said bars, they provide a casting-chamber for a columnwide section of base, substantially as shown in Fig. 3. The ribs F F are so located that when said casting-box is closed they enter the space between the bars B' and the bar D on one side and the bar B and the bar C on the other side and form a casting-chamber for sections of base of a half-column width, substantially as shown in the drawings.

In order to cast interlocking recesses in one side of said base-section and corresponding recesses in the engaging surfaces of the other base-section cast by this stereotype-box, I have provided the left-hand side of the bars Gand D with longitudinal beads h 72. at points near the casting-surface of the mold and have provided the opposite sides of said bars C and D with similarly-located corresponding longitudinal grooves These beads and grooves may so far as the features of my invention are concerned be shaped as shown in the drawings or otherwise. A groove G is formed along each side of the mold A in its plane surface a parallel to the central bars, with a depth below the surface a equal to the height of the outer face of the projecting flange of a base-section-clarnping strip 7c from the upper face of the base, as clearly shown in Fig. 3. The inner edge of said groove, in which the bars B B' are seated, is

rabbeted, and a plate H is secured in a depressed portion of surface a of the mold next grooves G in such manner that its uppersurface is flush with the plane a, and its edge overhangs the rabbeted portion of the groove G a distance equal tothe width of the clamping-strip flange, thereby forming a retainingslot a", in which the clamping-strip t may be secured in the position shown in Fig. 3, with its outer web-face against the bar B and its other parallel flange projecting into the casting-chamber of the side sections, so that when the metal is poured in said chamber the channeled clamping-strip 7:, is secured fast in said side sections of the stereotypebase. The outer or side bars B are each formed with a beveled portion which is adapted to engage and bear against this inclined side of the groove, so that when the cover is clamped to the mold and the said bars forced into their seats they will be moved toward and made to clamp the channeled clampingstrips in position.

As hereinbefore stated, the sides of said bars B B', C, and D are inclined to the surface a of the mold at an angle somewhat less than ninety degrees, so that the inner or proximate sides of the bars lean toward the opposing bar. The main part of the basesection cast' between these bars (in other Words, their upper plate-supporting portion) extends in a continuous stretch from bar to bar. Consequently as the metal cools after being run into the mold the continuous or upper portion of the base thus cast shrinks most, so that the sides of the base-sections when removed from the mold are in a plane at right angles or perpendicular to the platebearing surface, and when assembled for use these sides bear flat against each `other and form a rigid compact base.

What I claim as new isl. In a stereotype-casting box, the combination with the cover and mold, of parallel grooves formed in the mold-surface thereof near its side edges, whose sides are undercut, and side bars removably secured in said grooves, adapted to hold clamping-strips in engagement with said undercut sides.

2. In a stereotype-casting box, the combination with the cover and mold, of parallel grooves in the mold-surface near its side edges, Whose sides are undercut, and side bars removably secured in said grooves and adapted to lock clamping-strips in engagement with said undercut edges, the outer inclined sides of the grooves forming guides to properly seat said bars.

3. In a stereotype-casting box, the combination with the cover and mold, of parallel grooves iu the mold-surface near its side edges, whose sides are rabbeted, gage-plates secured in the rabbets, whose upper sides are iiush with the mold faces and whose inner edges overhang the grooves, and side bars seated in said grooves adapted to lock clamping-strip blanks in engagement with said plate edges.

4. In a stereotype-casting box, the combination with the cover and mold, of parallel clamping-strip-retaining grooves in the moldface near its side edges, side bars removably seated in said grooves adapted to lock the clamping-strips therein, and partition-bars parallel to said side bars, removably secured to said mold-face, the sides of the side and division bars forming angles of slightly less than ninety degrees with the mold-face.

5. In a stereotype-casting box, the combination with the cover and mold, of parallel clamping-strip-retaining grooves, side bars removably seated in said grooves, adapted to lock the clamping-strips therein, and partition-bars removably secured on said moldsurface, whose outer sides are a half-column width from the inner sides of said side bars, and whose inner sides are a column Width apart, said bar sides being adapted to form interlocking sides on base-sections, perpendicular to the bearing-surfaces thereof.

G. In a stereotype-casting box the combination with the cover and mold, of pockets of half-column and column width therein, and removable bars forming the sides of said half-column pockets, adapted to lock channeled clamping-strips therein.

7. In a stereotype-casting box, the combination with the cover and mold, of outer pockets of halfcolumn Width and inner IOO IIO

pockets of column width therein, removable means to retain sheet-metal clamping-strips partition-bars secured on the mold-surface in said outer pockets.
